A $dc$ current of $26\:\mu A$ flows through the circuit shown. The diode in the circuit is forward biased and it has an ideality factor of one. At the quiescent point, the diode has a junction capacitance of $0.5\:nF$. Its neutral region resistances can be neglected. Assume that the room temperature thermal equivalent voltage is $26\:mV$.
For $\omega =2\times 10^{6}rad/s$ , the amplitude of the small-signal component of diode current (in $\mu A$, correct to one decimal place) is __________.
